. v To all whom it may concern:

Be it known that I, SAMUEL F. ARBUoKLn, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Adjustably-Hi'nged Tilting Reflector for Lamps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,-.i n which like nu merals refer tolike parts.

This invention relates to a lamp or headlight especially adapted to use on motor vehicles, motor boats and the like, and relates more particularly to that type of headlight which is tilted for directing the rays of light toward the ground.

The main object of this invention is to so construct the headlight that the tilting reflector may be mounted therein so as to direct the rays'of light projected thereby directly forward and downward, or if desired by the user may be adjusted so that the same operation and tilting movement of the reflector will cause the light to be directed downwardly and laterally or sidewise from the lamp to any desired degree. To accomplish th1s purpose, the reflector is pivotally mounted within a frame which may be adjustably positioned within the casing so that the reflector will be hinged on an angle, whereby its tilting movement will be oblique instead of erpendicular.

y means of this construction a tilting reflector may be built without increase in cost so that the user thereof may have his choice of projecting his rays directly downward upon tilting the lamp, downwardly'and laterally, or completely sidewise, as desired and may be able to make his own adjustment as to the degree of lateral projection to suit h s own desires without difliculty, whereby the varying dimming ordinances of different States may be complied with.

In the drawin s, which are made a part of this application, igure 1 is a central vertical cross section through the lamp showing it in position to project parallel rays. Fig. 2 is the same as shown in Fig- 1 with the re flector tilted forward so as to project the rays directly downward. Fig. 3 is'a side eleva- 44 of'Fig. 1 with a portion broken away. Fig. 5 is a diagrammatic front elevation showing the reflector in vertical adiustment. Fig. 6 is a diagrammatic front elevation showing the reflector in vertical adjustment. In the drawings there is shown a lamp casing 10 parabolic in form having a door rim' 11 mounted thereon in which is secured a lens 12 in any suitable manner; The casing 10 is provided with an outwardly extending peripheral flange portion 13 over which the rearwardly extending outer flange portion of the rim is adapted to telescope for slidably fixing said rim 14 to the casing, the inner portion of the rim 14 thereby extending rearwardly inside of the casing,.as shown in Fig. 2. The telescoping flange portion of the casing and the rim permit the rim to be turned about its axis upon the casing. The forward surface of the rim 14 is provided with a depression or groove in which a cord 15 is mounted for sealing the space between the front glass 12 and the rim 14.

The rearwardly extending outer flange portion of the rim 14, in which the flange 13 of the casing engages, is provided with a plurality of projections 16 spaced about the outer periphery of said rim and extending inwardly. The projections 16 are adapted to extend into the holes 17 provided about the periphery-of the flange portion 13 of the casing, and spaced apart'so as to permit a more or less minute adjustment of the rim 14 within said casing. The inner surface of the rim 14 is nickeled so as to provide a reflecting surfacein continuation of the reflector 19. The rim 14 is provided with a bow -2O consisting of a metal strip fixedly secured to the periphery of said rim in the line of the vertical axis extending therethrough, and extending around and spaced apart and rearwardly from the rear of the parabolic reflector 19 so as to inclose said reflector in a plane through its vertical axis.

The reflector 19 is hinged at its bottom within the rim 14 by means of spring hinges to permit the reflector to tilt forwardly and upon the bow 20 so as to engage a projection 23 on the upper rear portion of the reflector 19 so that said reflector is normally forced" downwardly into tilted position, as shown in Fig. 2 under a constant spring tension. For

' fold of an internal combustion engine, not

shown herein, upon the release of said suction, the spring 22 causing said reflector to be tilted forwardly, as shown in Fig. 2. In the construction and operating mechanism above described, the mounting of the reflector and its operation is such that itmay be controlled so as to project the light either vertically or parallel, or oblique as desired. It will, therefore, be seen that the user of a lamp can make his own adjustment to suit his own desires, merely by turning the-rim 14 within the casing until the projection 16 engages in the desired hole 17,

whereby the reflector would be obliquely hinged, and, therefore, project the rays'of light both downwardly and laterally when tilted.

The invention claimed is:

In combination with a headlight having a casing and a source of illumination therein, of atilting reflector mounted within said casing, a frame upon which said reflector is mounted, means for actuating said tilting reflector, said casing'and frame having a plurality of indentures and projections about the peripheries. thereof, so positioned as to engage each other, whereby said frame may be turned in any desired position within said casing and locked therein for directing the projected rays of light downwardly and laterally.

In witness whereof, I have hereunto afiixed my signature.

SAMUEL F. ARBUGKLE.
